A fabulous consequence of raising our daughter as a bilingual with my non-native language is that her Papa is picking the language up by osmosis.
Papa had a French tutor for a few years until last September when his tutor could no longer provide lessons. Since then, outwardly his language learning had come to a halt. As we all know, language needs to be nurtured and even a native language speaker can lose their skills if they stop actively using their language for prolonged periods of time.
But Papa's nature is to listen and soak up.... quietly and diligently without making a fuss...and then, suddenly... I realised - he has been soaking up the conversations between Poppette and I and now understands so much more than he ever did. To the point where, should I say to Poppette in French, "Let's ask Daddy to go and run your bath and put on the bubble machine" I don't even have to translate anymore.... Papa just gets up and gets on with his little mission... it's brilliant to see another facet of language learning in action.
